It's a bit weird, I have been on the website and they add a free air filter kit but charge you £14.95 for it making it £213.95 I then added your code which was excepted, but it only gave you a discount of £34.95 which still does not add up to 20% also I could not remove the filter from the cart.

Yeah, the filter is free. What they do is they add it to the total and then deduct it in the total bringing it all down to £199. Then add the code in which takes it to £179.

It was £20 off not 20%, my mistake, I've amended the title accordingly now. Oops.
